The NI4CE-B DV UHF Digital Voice Repeater

http://dstar.ni4ce.org is the permanent home of all NI4CE D-Star information, links and FAQ's.

The NI4CE B DV Repeater at 444.425 went live on the air June 14th, 2008. The repeater operates at our Riverview, FL site at 880ft above sea level (805ft above ground level). There is no coax loss as the repeater is platform mounted in a environmentally controlled cabinet only feet from the antennas. Photos of the installation are online in our photo album. The system is running on a TX/RX T-Pass multicoupler/combiner system to permit the D-Star repeater and the 442.550 analog NI4CE repeater colocated at the same site to share the same set of antennas on the tower. Feedback from users confirms our estimated coverage map shown below matches up almost perfect with ground results. You will need a D-Star digital voice radio to participate on this repeater. Additionally, this system is operated completely seperate from the analog NI4CE system, they are not linked.

Our system is also gateway enabled. If you have already registered your call on a G2 gateway elsewhere, you are already able to use our gateway. To program your radio to use our gateway, you'll need to set RPT1 to NI4CE(space)(space)B and RPT2 to NI4CE(space)(space)G (the two spaces are important). Now if you have never used a D-Star gateway, you'll need to register your callsign on our gateway. Visit https://dstar.ni4ce.org to self register yourself on the gateway. The security certificate is self-signed for that page, so just press OK or continue to proceed when prompted. Once you agree to the terms of usage for our gateway, and enter your information on the registration page, you will need to wait to be authorized by us before continuing. We'll notify you via e-mail when you have been authorized. You'll then need to log back in and setup your radio in the personal info page, info on how to do this will be in the e-mail we send back to you. If you do not understand this process, just drop us an e-mail and we'll help you thru the process best we can.

Information regarding recent usage of NI4CE B


Commonly asked questions and policies about NI4CE B

  • In order for stations on far repeaters to know you are calling thru a gateway, please use the following commonly accepted format: "(yourcall) (theircall or CQ) calling on (repeater you are on) port (B for UHF, C for VHF)". Here's an real example... "ki4swy kg4yzy calling on ni4ce port b". This will prevent far users from answering you without knowing that they need to change the urCall in their radio be heard on the repeater you are on.

  • NI4CE B particpates in the weekly Florida D-Star net on the REF001BL, every Wednesday from 9pm-10pm local time. Join us for the net, technical questions are answered, and discussions on how to grow the usage of D-Star in Florida are common topics.

  • If you notice that once you setup your radio with NI4CE B that you do not see your callsign show up on the national last heard callsign website for d-star, this is normal for our system. The operators of this website would not disclose all the uses of their data collection, so we decided to not participate. We instead have a basic interface to display a last-heard interface for our local gateway, and its link is listed above. This does not affect gateway functionality at all, only that one website.

  • We ask that you do not attempt to do file transfers thru the repeater with programs like D-Rats. The chat (short message) portion of any of these programs that piggy back your text with mic PTT's is permitted, just not full file transfers.
